1D Circular Linear Microlens Array

Key Features Of  Coligh’s Linear Microlens Array
1. All plano-convex lenses are uniformly arranged along the X-axis, suitable for collimating and shaping rod-shaped or line-shaped light sources.
2. The lens design features aspherical lenses.
3. It can form linear light spots, making it ideal for applications such as scanning, line-array lasers, and fiber arrays for precise focusing or uniformizing light sources.
3. The function of each plano-convex circular sub-unit lens can be used for aberration control and adjusting the angle, focal position, and intensity distribution of light.
4. The circular sub-lens array maximizes the effective light transmission area.
5. It is highly suitable for integration into laser modules and optical communication modules for light collimation and fiber coupling.

1D Linear Microlens Arrays Applications:

• Light Collimation: In VCSELs and laser diodes, the laser emits a highly divergent beam. Through a linear microlens array, each sub-lens can collimate or focus a single laser beam, enabling the collimation or shaping of multiple divergent beams into uniformly distributed light rays and linear spots.


• Fiber Coupling: In multi-core fiber arrays and VCSELs, fiber coupling requires high alignment accuracy. A linear microlens array can be placed between the light source array and the fiber array to focus light onto the fiber endface. By adjusting the spot size, controlling the divergence angle, and other parameters, coupling loss can be minimized.
